Mortuary + Bolas's Citadel + Carrion Feeder + Crookshank Kobolds

Mortuary

Bolas's Citadel

Carrion Feeder

Crookshank Kobolds

How it works

1. Activate Carrion Feeder by sacrificing Crookshank Kobolds
2. When Crookshank Kobolds dies, Mortuary triggers, putting Crookshank Kobolds from your graveyard onto the top of your library.
3. Resolve the Carrion Feeder ability.
4. Cast Crookshank Kobolds from the top of your library by paying 0 life.
5. Repeat.

This delightful loop turns zero-mana creatures into an endless engine of sacrifice by leveraging Mortuary to constantly recycle your fallen fodder right back to the top of your library. From there, Bolas's Citadel steps in as the ultimate command center, letting you peer into the future and effortlessly cast those same recycled threats straight off the library using your life total instead of mana. You fuel this entire mechanized recursion by sacrificing Crookshank Kobolds to Carrion Feeder, generating an unstoppable cascade of triggers, pumped-up counters, and storm count without ever running out of ammunition.
